New subject: dde problems

Oct. 30, 2001

      Eric,

thanks for the pointers.  I removed the ms versions of the user32, kernel32
dlls.

I have attached a log file, containing the last ~100 lines of wine execution.
(the command I ran was "wine --debugmsg +dde,+relay --managed ./LOGOS.EXE")

am I doing something wrong if wine locks up my computer about half of the time
that I try running this app?  sometimes I can go back to a virtual console and
kill the wine processes(which in turn kills X, annoying but not so bad since xdm
kicks in), but often I have to reach for the power button.
